256986 Description of the Microsoft Windows Registry


SUMMARY

When a group policy is being processed on a Windows-based computer, client-side extensions are the components that interpret the stored policy and make the appropriate changes to the environment. In troubleshooting a given extensions' application of policy, the administrator can view the configuration parameters for that extension. These parameters are in the form of registry values.

MORE INFORMATION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.


Each client-side extension is identified by a subkey beneath the following path:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions


The subkey name takes the form of a Globally Unique Identifier (GUID). For more information about identifying registered group policy client-side extensions, see the following article in the Microsoft Knowledge Base:

216357 Identifying Group Policy Client-Side Extensions
